June 29, 2023June 30, 2023 Pooja Kashyap

When it comes to data-heavy applications and sustainable computing, photonic chips have emerged as a promising technology. The use of photonic circuits, powered by laser light, offers an edge over traditional electronic circuits. Some of its remarkable advantages over electronic circuits are: Speed of light: Photonic chips make use of light to transmit and process information, which of course happens at the “speed of light”. Thus, leveraging the feature of light makes them move faster than electrons in electronic circuits.

Capsule X-Ray Dosimeter for Real-time Monitoring: Radiotherapy

April 19, 2023April 19, 2023 Pooja Kashyap

Radiotherapy is all about precision in targeting tumor tissue while minimizing damage to healthy tissue. To deliver precision radiation requires real time monitoring of the dose till the time it is absorbed. The task is quite challenging, especially if it is in gastrointestinal tract. The dynamic nature of the region makes it nearly inaccessible. Current approaches used for tracking biochemical indicators including pH and temperature are insufficient to give out comprehensive evaluation of radiotherapy.

April 12, 2023April 12, 2023 Pooja Kashyap

Antineutrinos falls under the category of elusive particles. They are extremely difficult to detect due to their weak interaction with matter. These exotic particles have the same properties as neutrinos but with opposite charges. And have very little mass.

Dynamics between Quantum Entanglement: Coupling at a Distance

March 10, 2023March 10, 2023 Pooja Kashyap

Entanglement is a unique and powerful feature of quantum mechanics. It allows two or more particles, such as photons of light, to become correlated in such a way that the state of one particle is immediately determined by the state of the other particle, regardless of the distance between them. This phenomenon has been studied extensively in the field of quantum physics. It has important implications for the development of quantum technologies such as quantum cryptography and quantum computing.
